Abstract

A simple and fairly standardized technique of extracting volatile and semi-volatile substances from raw samples in liquid or solid form is headspace analyzes [1]. A sample is placed in a vial that is sealed by a septum and cap and heated in an incubator for a specific time. Once the content of the vial has reached equilibrium a sampled is extracted and injected into the injection port of a GC. LEAP’s specific equipment the CTC COMBI PAL performs all the tasks for this extraction method unattended. For a sequence of samples up to 96 the COMBI PAL will schedule the vials to be in the incubator/agitator for the same amount of time before a precise sample of headspace gas is extracted by a heated syringe system for a subsequent appropriate injection into a GC. Many variables are programmable over a validated range. 1ml, 2.5ml and 5ml syringes and a solvent-less solid phase micro extraction system are the tools that can be mounted in the injection head.

Some Advantages of Headspace Analysis

  1. Limited sample preparation
  2. Improves detection limits
  3. Reduction in method development times
  4. Reduction of matrix interference from sample matrix
  5. Extended life of the GC column
  6. Reduction of instrument down time
